WiFi On? Data Off?

This is absolutely redundant and unnecesary, when the phone connects to a wifi, it disables 3g/LTE data connection by itself. When you connect to a wifi you can see how the 3g/H/H+ icon above radio signal dissapears. The radio chip inside this phones can be used in Wifi mode or 3g/4g mode for data connection, but not both at a time. It is technically not possible.

HOWTO: Change Your IMEI Number

If you have damaged your /efs partition, then you can recover your EFS and IMEI Number.

HOWTO: UnRoot and ReRoot or Toggle Root

If you would like Android Pay or Pokemon Go to work on a rooted phone, then you need to just delete or move the 'su' binary from the folders it is located in.

I initally did this using 'ES File Exporer' Root Explorer feature, but once you do it, you cannot do it BACK again.

So, I came up with a better method using a laptop and a cable.

You will be logging in to the phone as root, remounting the system folder as read-write, creating some folders, moving the 'su' binary to those folders, and then remounting the system folder as read-only. We then download a copy of the 'su' binary to our laptop for good measure. Then, we test that we can pass the 'SafetyNet' test using a free simple no-ads app from the Play Store.

These instructions are at your own risk. You have been warned if you brick your phone. I accept no responsibility.
